  • a first and second folding blade cylinder is arranged, wherein the signatures are stripped by the products of the second folding blade optionally by means of bands.
  • DE 36 36 244 C2 discloses a folder with a pivotable stitching cylinder, which interacts selectively with a first or second jaw cylinder.
  • DE 44 07 375 A1 discloses a folder with at least one Jaw cylinder and a cooperating in a working position with the jaw cylinder first folding blade and a second folding blade, wherein the second folding blade from the working position is movable into a rest position.
  • the invention has for its object to provide a folder.
  • the displaceable folding cylinder is mounted between two side parts which are pivotable against side frames of the folder, a modular design of the folder is made possible.
  • the use of a dedicated motor to drive the displaceable folding cylinder enables it to decouple its movement from vibrations caused in the folder by variably loaded other rotationally driven parts such as a cutting or puncturing roller.
  • Another advantage of using the dedicated engine is that, unlike a common drive of folding cylinder and jaw cylinder by tooth engagement, by suitable control of this motor, the phase angle of the folding cylinder relative to the cooperating with him jaw cylinder is easily changed.
  • a coupling of the rotation of the motor to the width of the jaw gap can be provided such that a folding blade of the folding cylinder engages centrally in each width of the jaw gap in this.
  • the folder is thereby very easy and quickly adaptable to the processing of signatures of different thicknesses.
  • Another advantage is that the assembly with a second transverse fold no Significant influence on the design of the basic unit of the folder that is, that the usual bearing holes and the necessary for the gear drive oil space omitted and do not require an increase in the racks of the folder.
  • the folder further comprises a stationarily mounted folding cylinder.
  • the stationarily mounted folding cylinder can then serve to produce a first transverse fold on the product, whereas the displaceable folding cylinder can be used to produce a second transverse fold.
  • z. B. usually a large part of the circulation of daily newspapers, which is intended for subscription or for sale on the street, is made with a simple transverse fold, for that part of the edition, which is intended for the mail order, a second transverse fold is required to To bring the newspaper to a format suitable for mailing.
  • the folder according to the invention allows the production of the newspaper with or without second transverse fold, being pivoted for the support part without second transverse fold of the movable folding cylinder in the rest position and its drive can be switched off when the folder is running.
  • the jaw cylinder have pairs of jaws, the second folder of one pair cooperating with another folding cylinder, respectively.
  • This allows a simplification of the product guide, because in such an embodiment, a signature can be picked up by a holding device of the two folding cylinders and the signature folded by pushing into the gap of the first jaw by means of the folding blade of the folding cylinder and transferred to the jaw cylinder; Subsequently, the folded product in this way can be pressed by a folding blade of the other folding cylinder in the gap of the second folding door of the pair and so get its second transverse fold, without requiring a transfer to another cylinder is required.
  • the finished folded product can therefore be transferred directly from the jaw cylinder to a tape guide system or the like, and product promotion is simplified.
  • the two columns of the two cooperating Falzklappencovere are mutually advantageously circumferentially adjustable.
  • the grippers adjust in the folding cylinder.
  • Fig. 1 shows a schematic section of a folding apparatus of a rotary printing press.
  • a in the folder coming from a (not shown) Forming web incoming train 1 or a multi-web strand initially passes a pair of draw rollers 2 and then reaches a gap 3 between a cutting cylinder 4 and a stationary mounted first folding blade 7.
  • the cutting cylinder 4th carries at its periphery knives, which cooperate with knife grooves of the first folding blade 7 and cut the web 1 into individual signatures.
  • the individual signatures are detected by a holding device of the first folding blade cylinder 7, such as a gripper or puncture needles, and the signature is thus guided in the counterclockwise direction of the figure between the first folding blade cylinder 7 and a first guide plate 6 embracing the lower region of the first folding blade cylinder 7.
  • a holding device of the first folding blade cylinder 7 such as a gripper or puncture needles
  • the first baffle 6 terminates in the vicinity of a gap 8 between the first folding blade 7 and a jaw cylinder 9.
  • This jaw cylinder 9 has at its periphery a number of first jaws 11, which are equally spaced in the circumferential direction.
  • the jaw cylinder 9 has three first jaws 11 at an angular distance of 120 °.
  • the distance between two first jaws 11, measured on the circumference of the jaw cylinder 9, corresponds to the length of an unfolded signature.
  • the first jaws 11 each have a folding jaw cylinder 9 stationary strip-shaped jaws 12 and a coupled with the rotational movement of the jaw cylinder 9 pivotable jaws 13.
  • the coupling of the movement of the pivotable jaw 13 to the rotation of the jaw cylinder 9 is effected by means of a in Fig. 1 not illustrated cam.
  • This opens the gap of the first jaw 11 shortly before it reaches the gap 8, so that a folding blade mounted on the first folding blade 7 during the passage through the gap of the first jaw 11, the signature carried by the first folding blade 7 signature in the gap of the first jaw 11 can push into it.
  • This creates a first, central transverse fold on the signature.
  • the folding blade of the first folding blade 7 is retracted, close the jaws 12; 13 of the first folding door 11, so that the signature remains stuck in the first folding door 11 and is thus taken over by the jaw cylinder 9 and transported further.
  • a second baffle 14 closes off the exit gusset of the second gap 8. It serves to fold over the front half of the signature released by the holding device of the first folding-blade cylinder 7, so that the signature with the fold advancing from the jaw cylinder 9 is further conveyed.
  • Fig. 1 shows a signature, designated 16, in this stage of processing, wherein the formerly leading part 17 of the signature 16 along the second baffle 14 along sweeps.

  • This guide or pressure element 18 is located in the input gusset of a third gap 10, which is defined between the jaw cylinder 9 and a second folding blade 19.
  • This second folding blade cylinder 19 carries on its circumference two diametrically opposed holding devices, here in the form of grippers 21. Since the number of grippers 21 and the folding blade 22 is smaller than that of the first jaws 11, and the diameter of the second folding blade 19 in Ratio smaller than that of the jaw cylinder 9. This facilitates the arrangement of the two folding blade cylinders 7; 19 and described later on a tape guide system 27 on the circumference of the jaw cylinder. 9

  • the second folding blade 19 also carries two folding blades 22.
  • the distance between the gripper 21 and subsequent folding blade 22 on the second folding blade 19 is adjustable and is conveniently set to a quarter of the length of the signature 16 to the folding blade 22 a second transverse fold in the already once transversely folded signature 16 in the middle to bring.
  • This second folding blade cylinder 19 may have at its periphery a plurality of equally spaced holding devices, here in the form of grippers 21 and the number 2. In the same manner as those of the holding devices and the folding blades are placed, according to the format length equidistant from the holding devices , The smaller the number of holding devices or folding blade, the smaller the design of the second Fatzmesserzylinders be performed. In the least case, a holding device and 1 folding blade can be present.
  • the phase of the generation of the second transverse fold is shown in Fig. 2 with reference to a partial section of the folder.
  • the first transverse fold of the signature 16 is lifted by the gripper 21 from the surface of the jaw cylinder 9; the first jaw 11 is empty and open.
  • a second folding flap 23 is arranged on the circumference of the folding jaw cylinder 9 at a distance from the first folding flap 11, which corresponds to the distance between the gripper 21 and the folding blade 22 on the second folding blade cylinder 19. Also, the distance between the first and second jaw 11 and 23 is adjustable.
  • the folding blade 22 pushes the signature 16 in the open gap of the jaw 23 and the signature 16 is clamped in the gap. At the same time, the gripper 21 releases the first transverse fold of the signature 16.
  • Guide brushes 24 are arranged in the output gusset of the gap between the second folding blade cylinder 19 and jaw cylinder 9. As can be seen in Fig. 3, they serve to pivot the two legs of the now double folded transverse signature 16 against the surface of the jaw cylinder 9 and so to complete the folding process.
  • the product 26 which has been folded to completion after passing through the gap between the guide brushes 24 and the jaw cylinder 9 can be seen in FIG.
  • a belt guide system 27 shown schematically in FIG. 1 with belts 29 guided around rollers 28 takes over the product 26, which is released by the second folding door 23 approximately in its position shown in FIG. 2, and feeds it to a paddle wheel 31, which supports the Product 26 skimmed in a conventional manner on a belt boom 32, wherein the guide tongues 100 are pivoted at a distance from the stop 101, which corresponds approximately to the length of the product 26.

  • the second folding blade cylinder 19 is pivoted about an axis 33 at an angle of about 105 ° to the working position, instead, a third guide plate 34 is pivoted onto the jaw cylinder 9 and thus forms a continuous guide gap 36 for the signature 16, the extends substantially without interruption from the second guide plate 14 to a guide body 37 and further to the first roller 28 of the tape guide system 27.
  • the third guide plate 34 prevents in this way that the freshly folded signature 16 unfolds on its way from the end of the second baffle 14 to the top of the guide body 37 again when the second folding blade 19 is in its inactive position.
  • the guide tongues 100 are pivoted away at a distance to the stop 101, which corresponds approximately to the length of the product 26.
  • second folding blade 19 and guide brushes 24 between production with single and double transverse fold can be switched. Since the second folding blade 19 has no more transport function in the production with a simple transverse fold, its drive can be turned off in the idle position, even if the folder operates.
  • Fig. 5 shows in detail the structure of the guide or pressing member 18. It comprises a support 38 which is fixedly connected to a (not shown) side part (74, see Fig. 7), which at the same time a holder for the axis 33 of second folding blade 19 forms and carries the Leitbürsten 24.

  • a spring 48 e.g. a coil spring 48 exerts a torque in a clockwise direction on the pivot arm 39.
  • the setting of the threaded pin 43 specifies the maximum distance by which the roller 41 can move away from the latter when passing a signature 16 between it and the jaw cylinder 9 by pivoting the pivoting arm 39.
  • This maximum Distance is expediently set to a value which corresponds with slight play to the expected thickness of the simply cross folded signature 16. If, in the case of a Textilstopfers the thickness of the signature 16 is greater, and the roller 41 is pressed over the predetermined by the threaded pin 43 degree up, thereby the entire assembly from the working position pivoted upward, and damage to the sensitive moving parts of Jaw cylinder 9 and second folding blade 19 is avoided.
  • a servomechanism may be provided which measures the force transmitted from the roller 41 to the carrier 38 and, when a limit is exceeded, drives an actuator to swing the second folding blade cylinder 19 out of its operative position.

  • the gas spring 75 alone takes over the function of lifting, in order to achieve a safety distance between jaw cylinder 9 and folding blade cylinder 19 at the time of unwinding, the gripper 21 and folding blade 22 protects. Until the time of coasting, the synchronous deceleration is fed by the remaining voltage from the DC link.
  • a second task of the guiding or pressing element 18 is to ensure a low-friction guidance of the signature 16. Due to its rotatability, the roller 41 exerts a significantly lower friction on a continuous signature 16 than would be the case with a stationary guide plate such as the guide plate 14. That's why they are working at the moment the transfer of the first transverse fold to the gripper 21 of the second folding blade 19 at most low braking frictional forces on the signature 16, which simplifies the transfer and improves its accuracy.
